Question

if p varies inversely as a square roots of d and p equals 6 when d equals 9 find the formula connecting p and d, d when p equals 2​

Answer 1

• p = 18 / √d
• d = 81

Explanation:

p varies inversely as a square roots of d:

• p = k / √d

p equals 6 when d equals 9:

• p = 6, if q = 9
• 6 = k / √9
• 6 = k / 3
• k = 18

The equation is:

• p = 18 / √d

Find d when p = 2:

• 2 = 18 / √d
• √d = 18/2
• √d = 9
• d = 9²
• d = 81
